Francis Trigge Chained Library

The Francis Trigge Chained Library is a library in Grantham, Lincolnshire, England which was founded in 1598.

In 1598 Francis Trigge, Rector of Welbourne, near Leadenham in Lincolnshire, arranged for a library to be set up in the room over the South Porch of St. Wulfram's Church, Grantham for the use of the clergy and the inhabitants of the town and Soke. The borough was responsible for furnishing the porchroom and Trigge undertook to supply books to the value of "one hundred poundes or thereaboutes". The two vicars of North and South Grantham, together with the master of the local grammar school (now The King's School, Grantham) were to control the use of the library, and took an oath to abide by the rules. The original documents still exist and are deposited within the Lincolnshire Archives. The library was the first in England to be endowed for use outside an institution such as a school or college. It is perhaps slightly misleading to call it "the first public library" but nevertheless its use was not the prerogative of a private group.

The library has always been in the parvise over the south porch, originally the dwelling chamber of one of the vicars, with a fireplace, a small sink and an oriel window that provides a view of the nave of the church. A list of books made up in 1608 and still extant, contains 228 titles, but some of these prove to be works bound together. There are now 356 separate items catalogued. Some of these have been added over the years, including the works of the Cambridge Platonist and Cartesian Henry More, given by him during the 17th century. He was a native of Grantham and attended The King's School where, some forty years later, Isaac Newton was a pupil.
